EPA’s Office of Water (OW) is developing a technical support document on methods and approaches for developing numeric nutrient criteria for Florida’s estuarine and coastal waters, downstream protection values in streams to protect those waters, and criteria for flowing waters in the south Florida region (including canals). EPA has asked the SAB to conduct the external peer review of the draft technical support document, “Methods and Approaches for Deriving Numeric Criteria for Nitrogen/Phosphorus Pollution in Florida’s Estuaries, Coastal Waters, and Southern Inland Flowing Waters.”
